Direct answer: The timeline varies with payer enrollment, data access, interfaces, clearinghouse setup, open work and staffing. A practice should plan discovery, configuration, testing, cutover and stabilization as separate stages with named owners.
Stage 1: inventory systems, contracts and open work
Confirm termination notice, data-export rights, current reports, provider and payer records, interfaces, bank connections, open claims and old A/R. Use the contract review checklist before assigning a cutover date.
Stage 2: configure and test the new workflow
Set up providers, locations, payers, fee schedules, users, clearinghouse routing, remittances and reports. Test clean and failed transactions. The integration plan helps verify that corrections, rejects and missing records become visible.
Stage 3: cut over without losing unfinished work
Decide which organization owns claims already submitted, new charges, denials, refunds and patient balances. Reconcile encounters to claims and claims to acknowledgments during the first cycles. Keep access to former-system reports for validation and audit needs.
